Abstract

The invention discloses a cultivation method for high-quality nursery stock of sterculia nobilis. The cultivation method comprises the following steps: preparation of culture medium, transplanting, light and nitrogen treatment, shading treatment, nitrogen element fertilising treatment, and measurement of growth shapes. The best light transmittance ranges from 39.0 to 43.0% and the best nitrogen element level ranges from 3700 mg / plant to 4300 mg / plant. The cultivation method for high-quality nursery stock of sterculia nobilis has the following beneficial effects: the combination between illumination conditions and application of nitrogen fertilizers with best economic benefit is obtained so that utilization efficiency of nitrogen fertilizers is increased and application of nitrogen fertilizers is reduced; therefore, the theory foundation and technical reference are given to the early-stage fast cultivation of nursery stock of sterculia nobilis; reform of the industrial structure in rural areas is prompted; the industrial chain in the forestry is increased; more employment opportunities are provided for the society; and the cultivation method has great social benefit.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for cultivating high-quality apple seedlings. Background technique [0002] Pingpo is native to southern my country, and its scientific name is: Sterculia nobilis Smith. It is an evergreen tree in the family Sycamore. Pingpo is native to my country and has a long history of cultivation, especially in the Pearl River Delta of Guangdong Province. It is also grown in Southeast Asian countries such as India, Vietnam and Indonesia. Pingpo is also known as water hyacinth fruit, Qijie fruit, pinpo, Pan'an fruit, and nine-layer skin, etc. It is not used for commercial cultivation, and it is mostly sporadic [[]]. Its fruit, wood and skin have high economic value: the kernels of apples can be eaten as dried fruit, and can also be made into cakes like chestnuts and used as cooking side dishes. They are rich in nutrients, such as: amino acids, proteins , vita...
